The user will have to subscribe (`follow') the bank's Twitter handle and register for the facility, it said.

For fund transfer, the sender needs to know the beneficiary's Twitter handle. The sender will get an SMS with a unique code after the transfer; the beneficiary would need to enter it on the special webpage where he/she would be directed, to complete the transaction.

The bank is using the NEFT (National Electronic Funds Transfer) or RTGS (Real Time Gross Settlement) for the transfer and will soon be joining IMPS (Immediate Payment Service) mode too, he said.

The bank will not charge for such fund transfers but the sender will have to pay the fees as applicable for a NEFT or RTGS transaction.

Beneficiaries who have account with another bank will have to put in that bank's IFSC code to receive the payment,Sabharwal said.
